Shorthand syntax for duplicate validation rules

[jdarkins]

I often find cases where i am writing duplicate rules for form validations. Something along these sort of lines (not real code, just a basic example):

     $request->validate([
          'name' => ['required', 'string'],
          'email' => ['required', 'email'],
          'add1' => ['required', 'string'],
          'add2' => ['required', 'string'],
          'add3' => ['required', 'string'],
          'town' => ['required', 'string'],
          'postcode' => ['required', 'string'],
     ])

I think it would be great if this could work similar to a match where you can have multiple attributes in a single arm, like so:

$request->validate(
'name', 'add1', 'add2', 'add3', 'town', 'postcode' => ['required', 'string'],
'email' => ['required', 'email'],
)

I would love to give this a go myself but honestly wouldn't know where to start 😅

I appreciate it might not even possible / would be a breaking change to move away from passing in an array, I just think it could be a cool idea and couldn't find anyone else talking about it online.

I'd create class constants for these. Or we can add Rule alias feature where you globally define "requiredEmail" => 'required|email'.

Yeah fair enough

@jdarkins this is not valid php code. You forgot a set of []

$request->validate([
    'name', 'add1', 'add2', 'add3', 'town', 'postcode' => ['required', 'string'],
    'email' => ['required', 'email'],
])

But this is a syntax for match not for defining arrays.

Maybe this is what you wanted (csv keys):

$request->validate([
    'name,add1,add2,add3,town,postcode' => ['required', 'string'],
    'email' => ['required', 'email'],
])

[apih]

Why not write the rules like this?

$rules = [];

foreach (['name', 'add1', 'add2', 'add3', 'town', 'postcode'] as $attribute) {
     $rules[$attribute] = ['required', 'string'];
}

$request->validate($rules + [
     'email' => ['required', 'email'],
]);

@apih using + is not recommended. array_merge() or array_replace() should be used (taking into account that this is not a list).
